They were only used to play around in the yard and help put some time on the new engine. I have been rebuilding everything and the front shocks are a bitch to rebuild. The shock shaft tool and spring compressor broke so we had to order a new one. Been using them for along time. We ordered new springs and seal heads for them so it can be pretty much a stock shock. Those 99.99 shocks from vitos are junk they look like replacements but break to easy. We found a way to rebuild old ones like new again. It's never failed us just kind of a bitch to get the new parts to seal they have to be re machined to exact tolerance then no problems. My kid is 12 has done the entire engine himself, he also hand made a entire new electrical harness for it every wire replaced and soldiered its perfect plus he put a USB port on it for whatever. He has done everything on his quad but for putting the engine into the frame. I helped him with the engine and so far he's done a fabulously fantastic job to say the least. And all those aluminum parts are his ideas to make the front end look alot more sleek. He'll he made one for my 660 raptor while he was making his own actually looks great on mine as well. We restore old quads and dirt bikes that's what we do. Also all the kids in the neighborhood have their bikes fixed for free by us, they watch and learn how to do things so they can teach others the same. We tell them buy the parts we will help you replace them for free. Kind of hard to ask kids for ridiculous prices to fix there bikes for them so we do that for free if they help and learn how to themselves.
